Very bad service

why the hell should i deal with this bad service!!! Please investigte case reference***. End March 2015 i paid over R400 for a R299 contract!! This was queried on 5 March 2015 and your consultant confirmed that a mistake was made and that she can see they added a extra R29 to my bill which should be paid back to me. She could also see a R149 that was used to purchase data on 25 Feb 2015. This data was bought through my bank account and i have sent proof to show that it was deducted from my bank account. I want my R149 back as well as my R29. To top things of it takes forever to get through to a consultance and when i actually got a hold of one they couldnt assist because that person didnt deal with my case. They send me a sms saying they will get the consultant to phone me back the next day but im still waiting on the call. This is really bas service and im really considering closing this contract and moving to vodacom! Please refund me with what u owe me and i would also like 1gb data as a bonus for the inconvenience that was caused. Dont send me a sms to say that a consultant is gonna phone back then you never do.the consultant that logged my query is Liezl Mcdonald.
